Class FlowModel

java.lang.Object

org.springframework.webflow.engine.model.AbstractModel

org.springframework.webflow.engine.model.FlowModel

All Implemented Interfaces:

Model

public class FlowModel
extends AbstractModel

Model support for flows.

Defines exactly one flow definition. A flow is composed of one or more states that define the steps of a conversation. One of those steps is the start state, which defines the conversation's starting point.
A flow may also exhibit the following characteristics:

• Be annotated with attributes that define descriptive properties that may affect flow execution. (See AttributeModel)
• Be secured (See SecuredModel)
• Be a persistence context for managing persistent objects during the course of flow execution. (See PersistenceContextModel)
• Instantiate a set of instance variables when started. (See VarModel)
• Map input provided by callers that start it (See InputModel)
• Return output to callers that end it. (See OutputModel)
• Execute actions at start time and end time. (See EvaluateModel, RenderModel and SetModel)
• Define transitions shared by all states. (See TransitionModel)
• Handle exceptions thrown by during flow execution. (See ExceptionHandlerModel)
• Import one or more local bean definition files defining custom flow artifacts (such as actions, exception handlers, view factories, transition criteria, etc). (See BeanImportModel)
